sorry JP, the macro language is soooooo simple that it can just barely
handle integers
and then only when told explicitly via %eval.

> %DO f_x = 0.1 %TO 2 %BY 0.1;

The macro key-word that is unimplemented is <%BY>.

consider this kludge:

%local I F_X;
%DO I = 1 %TO 20;
%LET F_X = %sysevalf(&I/10);
